Apple II clock using interrupts from physical pendulum clock
A clock app for my Apple ][ clone in 6502 assembly, using interrupts generated by an inductive proximity sensor and a physical pendulum clock. I wanted to polish the code a bit more before sharing (I especially dislike the self modifying code part), but the computer seems to have developed a hardware problem lately and it keeps crashing (bad RAM chip most likely), so I am sharing as is.
In plain words
This is a clock application written in 6502 assembly for Apple II clone computers. It uses interrupts from an inductive proximity sensor connected to a physical pendulum clock to keep time. The code includes self-modifying sections the developer wishes to refactor. It is shared as-is due to hardware issues on the developer's machine. The project is available on GitHub for retro computing enthusiasts and assembly language programmers.
